Referring first to Fig. 1, the storm window embodies side rails in, a top rail ii, having laterally disposed flanges l2, a lower cross member I! and a transverse mullion l4 in the center. The inner ii for the reception of keys or shoes I6 mounted in a glazed sash l1 carried by the storm window frame structure. The upper portion of the storm window is provided with a glass pane l6 suitably secured in the side rails 10, the upper cros member H and preferably embedded in a mastic or cementitious calking material in 'a ledge I! in the cross-mullion H. The frame members for the sliding sash l'l. are a lesser thickness than the side and top rails l and i I so that the sash when elevated may slide freely over the glass pane l8 and still accommodate the sliding movement of a screen sash 20 supported in mitered grooves 2! (see Figs. 3 and 4) in the side rails in.

' The lower rail 13 of the storm window is provided with dowel pins22 adapted for engagement within holes drilled in the window sill adjacent the inner side of the storm window assembly. These holes are drilled to provide a substantial clearance over the dowel pins 22 so that the upper portion of the frame may be tilted outwardly as illustrated in Fig. when it is desired to wash the window adjacent thereto and also to facilitate the retraction of the storm sash into intimate engagement with the window casing when the storm window is mounted in place.

The side rails of the storm window are provided with screw eyes 23 arranged for the retention of spring wire clamping members 24 disposed adjacent the marginal edge of the frame and adapted for distortive assembly in interwoven relation with keepers such, for example, as the staples 25 mounted in the window casing edges of the side rails III are formed with grooves vldes access to the upper sash of the window in the building over which the storm window is mounted.

The sliding sash I1 is retained against lateral .movem'ent by the keys or shoes I. which are preferably formed of rods disposed for sliding movement within the side rails 36 and formed with depending end portions 22 engaged within the groove II in the side rails ID. The rods or shoes are further formed with similar depending end portions 23 adapted for torsional spring pressed engagement with pintles or keepers 24 set into the side rails 36 of the sash il. As will beseeninFig.g5.theshoes liaredisposedin contiguous relation with the pane of'glass 36 carried by the sash and are arranged for manipulation from the inner side of the storm window, that is for access from within the room for which the storm window is provided. When a shoe I6 is moved outwardly for engagement within the groovethe end portion 33 thereof will lie in contiguous relation with the inner edge of the side rail 36 of the sash and upon application of a torsional strain the opposed end of the rod or shoefl willbearagainsttheinnerwallofthe groove and may be held in frictional engagement therewith when the inner end of the depending arm 33 is snapped or sprung over the keeper 34.

The upper portion of the sash I1 is sealed against weather when arranged in its lowered position by a resilient weather strip 21 secured to the lower face of the mullion l4. As will be seen in Fig. 8,

the top rail of the sash i1 is of greater thickness than the side and bottom rails so as to form a ledge or abutment for engagement with the weather strip 31 when the window is arranged in its lowered position. The lower rail of the glazed sash I1 is formed with adepending tongue 38 arranged to overlie the outer face of a head 4 or rib 39 formed in the lower rail I3 of the storm (Figs. 9 and 10). The upper ends of the spring Y wires 24 are bent inwardly and engaged with holes in the side rails in of the storm window. The upper portion of the frame is provided with a. second spring lock wire 26 supported in the frame by a screw eye 21 and adapted to be similarly interwoven with hooks 28 mounted on the frame and keepers 29 mounted on the inner face of the rod will engage the eye 30 and support the frame in an outwardly tilted position as indicated by dotted lines in Fig. 10. This adjustment proformed of a resilient material capable of yieldwindow and thus form a weatherproof seal.

The screen 4!, as will be seen in Figs. 4 and 5, comprises a rectangular sash formed with beveled side rails 42, one of which is adapted for seated engagement in the mitered or dove-tailed groove 2i, the opposed side rail being cut away to provide a. flange 44 disposed to overlie the inner face of the contiguous side rail ill of the frame. The side rail of the screen sash having the flange 44 therein is provided with spring shoes or fingers 45 having one end thereof embedded in said side rail of the screen, the opposed end thereof being bent inwardly forre-entrant engagement within a clearance hole drilled in said side rail of the screen providing a looped portion for spring pressed engagement within the contiguous dovetailed groove 2|. The beveled portion of the opposed side rail is thereby urged into seated engagement with the dove-tailed groove in the opposed wall of the frame In preventing lateral displacement of the frame. When it is desired to remove the screen sash from the storm window assembly, pressure against the portion of the sash having the spring fingers 45 therein will permit collapse thereof and accommodate the release of the beveled portion of the frame from the dove-tail 2 I.

The inner face of the storm window is provided with a resilient molding strip 46 bradded or otherwise secured to the side and top rails in and II and adapted for intimate engagement with the face of the window casing. This strip may be ing under compressive eifort imposed thereon by the spring clamping bars 24 or if desired may be and. if desired, leaving the window suspended in the tilted position shown in Fig. 10. Next the window is retracted against the casing and the spring members 24 and 26 are interwoven with the keepers 2i and 29 respectively. Under certain climatic conditions the glazed sash I] may be elevated to the position desired and the screen adjusted to its lowered position to prevent insects from entering the room in which the assembly is installed. If on the other hand the screen is not required the screen sash ll may be moved to the top of the frame and the glazed sash adjusted vertically to attain the desired degree of ventilation. In either adjustment it will be noted thatthe sash l1 maybemoved independent of the screen 4| and that both will slide past the fixed pane of glass I 8.

As will be seen in Figs. 12 and 13, the modified form of bottom rail 60 embodies a resilient weather seal strip 8| secured in a groove H in the lower face of the rail.

The inner and lower faces of,the rail 80 are cut away to accommodate the assembly of the weather strip and the deformation thereof when brought into abutting relation with the sill 83.

Referring next to Figs. 14 to 20, the modified structure embodies frame members 69 and .10 with grooves II and 12 therein for the retention of the side members 13 and 14 ofthe glazed sash I1.

The bottom of groove 12 defines an acute angle with the outer face thereof and the edge of the contiguous side rail 14 of the frame I! is beveled to conform to said groove.

The opposed side rail 13 is engaged within the groove II in the frame member 69, said groove being substantially rectangular in cross section and of a suitable width to accommodate the slidable adjustment of the sash l1 therein. A retainin'g spring wire shoe 15 protrudes from the edge of the sliding sash side rail 13 in a gradual retuming arc, the free end thereof being in slidable engagement with the edge of said rail. As will be seen in Fig. 16 the spring wire 15, in its unstressed form, is disposed inwardly from the plane of the glazed sash. Thus the wire in its assembled position exerts an outward thrust on the rail 13 as well as a lateral thrust on the sash The outward thrust maintains a weathertight engagement of the face A of the rail 13 with the wall B of the groove H. The lateral cutaway to accommodate the operation of a spring shoe 18 as heretofore described. The opposed side rail of the screen is formed for interlocking engagement with a beveled tongue 19 defining the inner wall of groove H in the frame member 69. Fig. 17 illustrates a further modified form of spring wire shoe. 8| applicable to .both sliding sashes. Both ends 82 of the wire are. driven laterally into the edge of the flange 83, the intermediate portion thereof being of arcuate configuration and formed to protrude from said flange in a plane oblique to the plane of the sash, as shown in Fig.18.

As will be seen in Figs. 18 and 19 a notch 91 is formed in the glass retaining strip '92 to engage the ledge 40 in the upper rail of the glazed sash, thus accommodating the lateral adjustment and removal thereof. A recess 93 of the contour of the spring 8| is provided in the bottom of the retaining groove 94 to relieve the compressive effort of the, spring 8| when the glazed sash is moved for registration of the ledge 40 with the notch 9|. Hence when the spring is seated in the groove 94 the lateral thrust upon the sliding sash I1 is materially diminished and the .removal of the sash may be effected with very little efiort. The notch SI and recess 93 are disposed to be in operative position when the sliding sash is partially raised from its lowered position.

The improved storm window will obviously eliminate the handling of the screen element and will provide all the utilities and advantages thereof when used in mid seasons or in geographical locationswhere it is desirable to obtain the benefits of the storm window, variable ventilation and the use of the screen within the same period of time. The assembly will, moreover, avoid unnecessary handling of the screen when the window is employed for year around installation to attain the combined advantages afforded by the assembly. a

The improved storm 'window will obviously eliminate the seasonal removal and installation of the screen and sash members and the storage thereof. When screen protection only is desired, the sliding sash may be elevated and the screen lowered to its operative position. When storm sash protection only is desired, the positions are reversed, providinga completely weather sealed storm sash. However, any combination of sash ventilation and screen protection may be effected by intermediate adjustment of the glazed sash when the screen is in its lower position.

Although the foregoing description is necessarily of a detailed character, in order that the invention may be completely set forth, it is to be understood that thevarious modified forms disthrust on the sash forces the opposite side rail 14 thereof against the contiguous beveled groove, producing an outward component of thrust resulting in intimate engagement of the face A of the rail 14 and the wall B'of the groove 12. Removal of the glazed sash is efi'ected .by forcing the sash laterally to collapse the-spring wire 15, thus allowing the opposed side rail 14 to be swung free of the storm window frame.

The sliding screen sash shown in Fig. 14 comprises two side rail members I8 having flanges 11 thereon which are disposed in intimate overlapped relation with the inner faces of the frame members 69 and I0. The edge of one side rail member adjacent the flanged portion thereof is closed herein are intended for assembly in or with the storm sash and that the specific terminology employed in connection therewith is not intended to be restrictive or confining. It is to be further understood that various rearrangements of parts andmodifications of detail may be resorted to without departing from the scope or spirit of the invention as herein claimed.
